Re: lilypond "preprocessor"?

We need a copy so we can introduce the space time dumper code which boils down to a simple /include statement at the very top of the file.

You can do that via the -dinclude-settings option instead.

It looks like ly2video also removes any \break, \noBreak, and \pageBreak it finds in the input.

I don't understand why it needs to do this. \break and \pageBreak are ignored with #ly:one-line-breaking anyway.

Normally, you'd spell out the \unfoldRepeats and stuff in the input file directly.

I don't think the user should do this.  What I mean is that it's not user friendly.

ly2video or not, you need to unfold repeats as soon as you want correct MIDI output. I agree that requiring to do it explicitly is not very user-friendly, but auto-adding \unfoldRepeats sounds like solving the problem at the wrong level. Also, what ly2video does is not always correct since \score { \midi { ... } \music } is valid but \score { \unfoldRepeats \midi { ... } \music } is not — it would need to be \score { \midi { ... } \unfoldRepeats \music }.

Lastly, I'm not sure why ly2video wants to parse the header block but the --header option may help.
